The Pauli-Exclusion Principle Indistinguishability
With the lowest available, but taking into consideration the Pauli-Exclusion principle. So for helium (Z = 2), if you want both electrons in the ground state (n =1, l = 0), one electron must have spin-up and the other spin-down. ... Doc Retrieval

Chapter 5 Stellar Energy Production - University Of Tennessee
Chapter 5 Stellar Energy Production Since stars are composed mostly of hydrogen and helium, (Z = 1) will be easier to fuse than helium (Z =2). • In particular, we shall see shortly that main sequence stars are powered by thermonuclear processes that convert four 1H into 4He. ... Access Content
